Matheson wants to sell youless. For safety's sake. Hazardous gases, when used properly, can be perfectly safe. But you take a risk when you buy more than you need and store the surplus, or handle large bulk type containers. Because excess gas tends to be set aside and ignored, or handled by untrained personnel. Bulk type containers can also increase your risk potential in the event of a leak. The result can be costly or even tragic. That's why Matheson makes this simple but emphatic recommendation:

Buy exactly what you need to do thejob. For example, if you use one 1000pound bulk type cylinder per month, purchase ten 100-pound cylinders.

This minimizes the potential hazard per package. Or, if you need 5 pounds of phosgene for a project, buy only 5 pounds of phosgene and return the empty cylinder promptly. Don't buy excess and store it. If you like, we can arrange an automatic delivery schedule so that you will always have what you need on hand. Not more. Not less. We make buying the right quantity of hazardous gas easy, by providing all our gases in virtually any quantity—from standard size cylinders to our handy lecture bottles. And when you order your hazardous gas from Matheson, you have the added comfort of knowing that each cylinder and valve has been carefully prepared and inspected according to the highest standards in the industry.
